Question

Find the solution to the equation

a) 3y + 5 = 18
b) x/4 + 13 = 10
c) -6r +2 = 3r – 6:
d) 5x-(x + 3) = 5;
e) I - (y + 2) = -14 + 5(y + 3).
​

Answer 1

a) 3y=18-5

3y=13

3y/3=13/3

y=13/3

Answer 2

Explanation:

b)x/4 =10-13

x/4 = -3

4× x/4 = -3 ×4

x = -12

c) -6r -3r = -6-2

-9r = -8

-9r/-9 = -8/-9

r = 8/9

d)5x-x -3 =5

5x-x = 5+3

4x = 8

4x/4 = 8/4

x=2
